ABSTRACT
Objective: To observe the curative effect and reoccurrence prevention of mometasone furoate nasal sprays combined with montelukast on allergic rhinitis ( AR) . Methods:Totally 74 cases of patients with AR were divided into the observation group and the control at random. The patients in the observation group were given mometasone furoate nasal sprays combined with montelukast, while the patients in the control group were only given mometasone furoate nasal sprays for 4 weeks. The clinical curative effect and ad-verse drug reaction ( ADR) in the two groups were observed and compared, and the reoccurrence rates in the two groups after one-year following-up were compared as well. Results:The total efficiency in the observation group was 94. 59%, which was much higher than that in the control group (78. 38%), and the reoccurrence rate in one year was 22. 86% in the observation group, which was much lower than that in the control group (48. 28%) with statistical differences (P0.05). Conclusion: Compared with mometasone furoate nasal sprays, the application of mometasone furoate nasal sprays combined with montelukast in the treatment of AR can reduce the reoccur-rence rate with good security.
ABSTRACT
BACKGROUND: The choline acetyltransferase (CHAT) is the key synthetic enzyme for acetylcholine, and is the important symbol of the functional activity of the cholinergic system. There was a relationship of the cholinergic neurons damage with the pathogenesis of Alzheimer disease (AD) and the mild cognitive impairment (MCI). Whether or not the fimbria/fornix transection may affect the expressive variety of ChAT in different cerebral regions of rats (cortex, hippocammpi CA1, amygdala, Meynert nucleus) is very important for the recognition of the pathogenesis of AD and MCI and the establishment of experimental animal model of AD.OBJECTIVE: To observe the expressive variety of ChAT in different cerebral regions of rats with fimbria/fornix transection and discuss exploratorily the methods of simulative experimental AD.DESIGN: A randomized and control study.SETTING: Institute of Cerebrovascular Disease, Affiliated Hospital of the Qingdao University Medical College and the Department of Neurology, No. 1People' s Hospital of Jining.MATERIALS: The experiment was completed in the Institute of Cerebrovascular Disease, Affiliated Hospital of the Qingdao University Medical College from March to December 2003. Totally 14 adult healthy female Wistar rats aged 5 months were randomly divided into model group and control group with 7 in each group.METHODS: ① The bilateral fimbria-fornix of brain in model group were transected on the stereotaxic apparatus to set animal model. After opening the skull, at the coordinates, along the bregma posterior 2.2 mm-2.5 mm and lateral 1.0 mm according to the atlas of Paxinos and Watson, and the dorsal fornix, the anterior part of hippocampus and the fimbria were cut off with a double blade under visual inspection. Rats in the control group were not performed with fimbria/fornix transection, and the other procedures were completed as those in the model group. ② On the 28 day after the surgery, all rats were killed under anesthesia to take out the brain tissues and make coronary sections for histochemical observation in a immunohistochemical way. The expressions of the ChAT positive neurons were observed in the cortex, hippocammpi CA1, amygdala, Meynert nucleus, and the brown neurons under microscopy was the ChAT positive neurons.MAIN OUTCOME MEASURES: Expressions of ChAT positive neurons in the cortex, hippocammpi CA1, amygdala, Meynert of the basal forebrain in the model group and the control group.RESULTS: All the rats entered the final analysis without any loss. The expression of ChAT positive neurons in the cortex, hippocammpi CA1,amygdala, Meynert of the basal forebrain in the model group were distinctly decreased than that in the control group (2.97±1.45, 32.60±7.33, t=10.51,P ＜ 0.01); (6.83±2.41, 50.57±5.85, t=1 8.30, P＜ 0.01); (14.43±6.75, 35.43±10.49,t=4.47, P ＜ 0.01); (5.77±6.62, 48.77±7.10, t=1 1.72, P ＜ 0.01), and the differences were significant.CONCLUSION: Finbria/fomix transection can decrease the expression of ChAT positive neurons in many cerebral regions of rats, and can be used in a method of setting the experimental animal model of AD.
ABSTRACT
Objective To study the association between paternal CD3, CD4 and CD8 antigenecity to their pregnant spouses and the development of pregnancy induced hypertension (PIH). Methods Maternal serum from 15 women with PIH in the third trimester and 82 in normal pregnancies (16 in the first, 32 in the second and 34 in the third trimester) were incubated with paternal T lymphocytes. Monoclonal CD3, CD4 and CD8 fluorescent conjugated antibodies were then added and the percentage of paternal T cell differentiation antigen CD3, CD4 and CD8 were measured by flow cytometry. Results During normal pregnancy, the levels of maternal serum blocking antibodies on paternal CD3, CD4 and CD8 were (4.14?1.02, 2.02 ?0.24, 2.37?1.05)% in first trimester, (-0.29?0.13, 1.03?0.27, 0.65?0.23)% in the second trimester and (-1.33?1.47,0.15?0.01, -1.04? 0.37)% in the third trimester. There were significant difference between them( P
